un error en el setOnItemClick:
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {

Fragment fragment = null;

switch (position) {
case 0:
fragment = new Fragment1();------------>Aqui me da error a partir del =
break;
case 1:
fragment = new Fragment2();------------>Aqui me da error a partir del =
break;
case 2:
fragment = new Fragment3();------------>Aqui me da error a partir del =
break;
}

FragmentManager fragmentManager =
getSupportFragmentManager();------------>Aqui me da error :Type mismatch: cannot convert from android.support.v4.app.FragmentManager to android.app.FragmentManager

Hola Manu,

debes haber tenido algún problemilla al importar el código, porque si miras el código de mi ejemplo en GitHub (https://github.com/sgolivernet/curso-android-src/blob/develop/android-navigationdrawer/src/net/sgoliver/android/navdrawer/MainActivity.java) verás que los import que hace son:

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;

y no los que indicas en tu código:

import android.app.Fragment;
import android.app.FragmentManager;

Saludos.
